APPARATUS FOR MEASURING THE FLOW OF LIQUIDS.

SPECIFICATION forming part of Letters Application filed November 6, 1854. (No model.

'. To all whom it may concern:

Be 'it known that we, WILLIAM. ALFRED MORRISON BROWN, of Gnilford Street, wine and spirit merchant, and JOHN MEGsoN PORTER, of

Gookridge Street, architect, both in Leeds, in the county of York, England, respectively, subjects of the Queen of Great Britain, have invented certain new and useful Improvements in the Means or Apparatus Employed 1 for Measuring or Regulating the Flow of Liquids, (for which we have obtained a patent in Great Britain, No. 10,826, dated July 31, 1884,) of which the following is a specification, reference being had to the accompanying drawings, in which similar letters of reference indicate corresponding parts.

Figure 1 is a general View of the apparatus; and Figs. 2 to 12 are detail diagrams.

a is a barrel from which the liquid is being drawn by means of the pipe I). This pipe leads to the tap or cock 0. This cock has its plug formed with an elbow-passage, as shown at 0, Figs. 6 and 7. WVhen the plug is turned, as shown in Fig. 6, it allows liquor to flow from the cask a into the vessel (2 and stops it off from the spout 0; but when it is necessary to draw liquor out through the delivery-nozale 0 into a glass or other suitable measure for consumption, the turning of the tap for that purpose shuts off the supply from the cask a. The vessel d is formed with a glass or metal barrel 0r cylinder, the top and bottom covers being usually of metal. The lower cover is fitted at b to the end of the pipe 0 3 5 The top cover of the vessel (1 is fitted with two metallic rods, 6 6 which act as conductors of the electric current, hereinafter referred to. The rod 6 is connected with the top or bottom cover, or with both, and is in electric communication with the conductor 12, Fig. 7 either through the metallic parts intervening between said rod and conductor 11 or otherwise, and the rod 6 passes through the coverand is placed in electric communication with 5 the terminal 0 and is insulated from the metal cover.

f is a floating piston, which floats upon or Patent No. 314,914, dated March. 31, 1885.

rod without any non-conducting material. The rod 6 consists of an internal rod similar to 0, but surrounded with a series of rings of conducting material, r and non-conducting ma terial h. The fioatf, Figs. 2, 3, 4, and 10, is fitted to slide on the rods 0 e", and it also has a slight metallic conductor, f, as shown in Figs. 3 and 10. \Vhenf isin communication or contact with one of the rings g,the electrical current freely passes between the terminals 6 and 6; but when the conductorf is in contact with one of the non-conductors h the electric current is interrupted. \Vhen liquor is withdrawn from the vessel (1 through the tap c, the float descends, and, as it descends, the current is alternately completed and broken by the contact off with 6". An air-valve, i, is fitted in the cover to admit air when the piston isdescending and the liquor being withdrawn. XVhen the piston f is floated to the position shown in Fig. 2, the contact of the piston with the valve closes the latter and prevents the further egress ofair and loss ot'liquor. In Fig. 3 this valve is shown open.

Fig. 4 shows a modification of the vessel d, in which the rods are mounted above the cover, the conductorf being placed upon a rod, is, attached to the piston f and passing freely through the cover.

Fig. 8 is a diagram of the top cover of Fig. 4-, and Fig. 9 is a diagram of the top cover of the vessel (7.. (Shown in Figs. 2 and 3.)

Figs. 11 and 12 are respectively plan view and elevation of an ordinary counting apparatus actuated by electro-magnets. on m are the magnets.

a is an armature,which is alternately drawn and repulsed by the magnets.

0 is an upright bar pivoted at its lower end at the point p and carrying thepropelling-bar q and detent-pawl 1*, whereby the wheels andthe connected counting apparatus is actuated 0 in a manner well known. The spring at and regulating-screw t regulate the force applied to the bar 0, a curved plate-spring, a, bearing against the heels of the bar q and pawl r, serving to hold the latter in engagement with the 95 wheel 8.

The whole of the counting apparatus is placed in a boX, a, which may be kept locked, and wires 10 w are placed in position to communicate with the electro-magnets, the bat tery, and the tap a. The battery may be suitably inclosed in a case, as at A, Fig. 1, any ordinary battery or other electrical current being used for that purpose.

When the liquor is being admitted from 13113 barrel a to the vessel d, it is necessary to prevent electrical contact. This is effected by ineans'of the wire 00, Figs. 1 and 5, which is in communication with the battery. This wire is partly inclosed in insulating material at 1 The lower end of the plug, Fig. 7, has asmall metallic spring, 1), (shown also in plan in the same figure,) and a spring is fitted at 2 which presses down the plug.

WVhen the plug is turned, as shown in Fig. 6, to draw liquor from the cask and fill the vessel d, the spring o will be out of contact with the wire 00, and the electric current is thereby broken until the tap is again turned and the connection with x is made.

Our invention may be applied to wine, spirits, and all other kinds of liquid, and by its use correct indications of the quantities withdrawn are made, and fraud. is prevented. Having now particularly described and ascertained the nature of our said invention and in what manner the same is to be performed, we declare that what we claim is- 1. The combination of a receiving-tank provided with a float, an electrical conductor car ried by said float, a circuit-breaker for alternately opening and closing the circuit at certain stages in the movement of the float, a pipe leading from said receiving-vessel, a way-cock connected with said pipe, a pipe leading from a liquid source of supply and communicating with the receivingvessel through said waycock, a register having an electrical connection with said circuit breaker and closer, a battery for charging said electrical conductors,

and a wire leading from said battery to a point adjacent to said cock, whereby in the movement of said cock to permit the flow of the liquid into the receiver the flow of the current through the float circuit-breaker will be stopped and when the cock is moved to cut off the flow of the liquid the'current will be again established, substantially as described.

2. The combination, with the vessel d, of the rods 6 and a the conductors g and nonconductors h, arranged in alternation on the rod 6 the float f within the vessel, the conductorf, carried by said float, and the rods 0 and e", substantially as described.

3. The combination of the vessel (1, the rods 6 and 6 the conductors and non-conductors g and h, arranged in alternation on the rod 0, the float f, and conductor f, carried by said float, pipe 0", leading from vessel (1, the wayplug 0, connected therewith, the pipe 1), connecting with the way'cock, the battery, the wires w, through which a current passes to the rod efiand the wire 00, leading from the battery to a point adjacent to the plug of the cock 0, substantially as described.

4. The combination of the vessel d, the rods 6 and 6 the conductors and non-conductorsg and h, arranged in alternation on the rod 0 the float f, and conductor f, carried by said float, the pipe 0, leading from vessel (1, the way-plug 0, connected therewith, the pipe I), connected with the way-cock, the battery, the register, the wires 10, connecting the register with the battery and with rod 6 and the wire as, leading from the battery to a point adjacent to the plug of the cock 0, substantially as described.

In testimony whereof we have hereunto set our hands this 14th day of October, 1884.
